This invention, stated .in its broadest terms, relates to concrete construction and has more especial relation to means for supporting a screed with respect to metal lath and in interlocked relation therewith.

As at present practiced a Wood-blocking piece is wired to place upon metal lath and the screed r nailing piece is nailed to the wood-blocking-piece; I From an engineering view-point this is an unsatisfactory method of procedure for the following reasons lath.

(1) The distance from the lath to the top of the nailing piece is not always the .same.

' (2) There is nothing present with: which to interlockthe support with respect to the (3) Due to the fact that the blocking point is necessarily thm it very'frequently splits when the. nailing piece is nailed to it.

making it necessary to re-Wire a new-blocking-piece, thus rendering the whole operay rangement, and vorgani'zatlon of the instrution unnecessarily expensive.-

(4) A wood-blocking-piece is not a satis- .factory support since it displaces concrete" which is required for the strength floor structure. 1

The leading object of the present invention is to overcome the. above described disadvantageous features and provide a strucof the ture of the character under discussion in which my novel screed supports are first positioned upon and interlocked directly with metal lath and in proper alignment, after which concrete is poured upon the lath and around the positioned supports. By such construction not only am I enabled to use lighter and cheaper grade of metal thus reducing production and shipping charges but the cost of positioning the supports upon the iob is reduced. because of the ease and rapidity with which the same may be caused to engage with the slotted parts of metal lath. A further obje'ct'resides in the provision of a novel form of screed support whereby the results outlined in the leading object may be obtained.

A further object of the present invention resides in the providing oflgeneral details of construction and arrangement of parts as.

will hereinafter more fully appear.

The invention consists of the novel con-' struction hereinafter described and finally claimed.

These combined parts are made from several pieces of material, properly secured together, although I'prefer the integral structure. For illustrative purposes I have shown metal lath consisting of ribbed portions 7between adjacent ribs of which are a plurality of slotted portions'S bridged by webs 9, the slots and web's between alter nate ribs 7 being arranged in staggered relation. However, my novel screed support may g be employed in connection with other forms of slotted metal lath, 'In use With metal lath properly supported upon beams, not shown,

' an unskilled Workman may quickly and readily interlock screedsupports: with respect to the lath by insertion of the tongues 6 through the slots 8 and beneath the Webs 9, a screed support, thus attached, spanning three sets of Webs 9', as-clearlyshow1 1 in Fig 2. Because the various slotted parts of the manual are evenly divided, the various screed, supports may be readily aligned and they retain their original position Which is most desirable When securing screed T to place.
